2S LiFePO4 directly into Futaba BLS 251

Anyone powering a Futaba BLS 251 tail servo directly with an unregulated 2S LiIon source without popping the servo?
Some have opted for a 6V regulator using a 2S LiPo source. Others use a step down device just before the servo. I do have a Scott Grey Reactor, but I want to keep things simple.

The Futaba BLS 251 is rated for 4.8V only so I would use a voltage stepping device between the gyro & servo. I;m using the one from Align on a 2S Lipo rx pack. So far so good.
